Harry Potter fans flocked to social media sites on Thursday to celebrate the news that author J.K. Rowling will be taking a crack at adult fiction.

The best-selling author has announced that she will be returning to writing, and the content this time will be geared toward adults. Rowling will be working with a new publisher — Little, Brown and Company — for her latest book. No details about the name, storyline and release date are known at this time.

“Although I’ve enjoyed writing it every bit as much, my next book will be very different to the Harry Potter series, which has been published so brilliantly by Bloomsbury and my other publishers around the world,” Rowling said in a statement.

“The freedom to explore new territory is a gift that Harry’s success has brought me, and with that new territory it seemed a logical progression to have a new publisher. I am delighted to have a second publishing home in Little, Brown, and a publishing team that will be a great partner in this new phase of my writing life.”

Fans of the wildly popular Harry Potter series posted the news to sites such as Twitter and Facebook and made the announcement go viral.

Hashtags and keywords related to Rowling trended worldwide on Twitter, and the author become one of the most-searched terms on Google.

Even the fictional characters from Rowling's previous books such as Professor Snape and Voldemort sent out tweets with their reactions. Meanwhile, U.K.-based crime novelist Ian Rankin sent out a tweet suggesting that Rowling's novel could be crime-focused and set in Edinburgh, Scotland — his and Rowling's home town.

"Wouldn't it be funny if J K Rowling's first novel for adults turned out to be a crime story set in Edinburgh? My word yes," @Beathhigh tweeted.
